Aramid filter bag has high temperature resistance and long service life. It is the first choice filter material for bag filter in current high temperature filtering occasions. High temperature resistant aramid fabric bag has the characteristics of acid and alkali corrosion resistance, high temperature resistance, high strength, wear resistance, and folding resistance. function, and there are series products suitable for 200°C-250°C.

Features of high temperature resistant aramid filter bag 

1) Dimensional stability: The thermal shrinkage rate is less than 1% at a temperature of 200 °C, and it has excellent high temperature thermal stability.

2) Excellent temperature resistance: It can be used continuously at a temperature of 204°C, and can accept an instantaneous temperature resistance of 250°C.

3) Fire resistance: it starts to differentiate and carbonize at 400℃, the limiting oxygen index (LOI) is 30, neither spontaneous combustion nor combustion-supporting.

4) Chemical resistance: Low concentration of acid and alkali and most hydrocarbons will not affect it, even a small amount of fluoride will not corrode significantly; it is one of the accessories of asphalt concrete mixing dust collector.

Compared with chemical fiber high temperature resistant filter material, the cloth bag overcomes the shortcomings of chemical fiber filter material such as elongation, large deformation, low temperature resistance and poor corrosion resistance. Its size is stable, its strength is very good, and its price is lower than other high temperature resistant chemical fibers. Widely used in chemical formula, carbon black, building materials, steel, non-ferrous metallurgy, electric power and other parts. It has been proven to be widely used in high-temperature filtration fields, temporarily using high wear resistance and maintaining high strength. Widely used in asphalt, lime, iron and steel, drying, crushed stone, non-ferrous metal, lime, dust, metallurgy, plaster of Paris, plastic, carbon black, coke, etc.
